摘要
随着现代雷达技术的发展,数字波束形成(DBF)体制在雷达系统占据越来越重要的位置,多通道小型化接收机、高稳定频率合成等技术为DBF体制雷达的发展奠定了技术基础。文中分析了一种X波段DBF体制接收系统的设计方案,重点讨论了四个关键技术:动态范围的确定、多路小型化接收通道和频率合成器没计、激励源输出信号杂散噪声分析。文中设计的X波段接收系统,已达到预期性能指标及技术要求,其相关技术可推广应用至其他频段雷达接收系统。
With the development of modern radar technology, digital beam forming （DBF） system is playing more and more impor- tant role in radar field, the technologies of mini-multichannel receiver, high stability synthesizer, ete, provide a technique founda- tion for DBF-system radar. Design methods of a X-band DBF receiver are analyzed in the paper, four key technologies of receiver are discussed： determination of dynamic range, design of miniaturized multiehannel receiver and synthesizer and analysis for stray and noise of excitation. The X-band receiver has shown prospective performance and reached the technical requirements. Its tech- nology can be widely used in the radar receiver with other frequency bands.
